Optimized Layout for the TPS565201 EVM

 26 views

An optimized layout is important to the performance of DC-DC regulators. This application report focuses on improving the impact of thermal and switching spike voltage. First, the layout rule is discussed. Next, three different kinds of layouts are created, depending on the layout guide, using the TPS565201. Finally, by creating a PCB model and testing thermal, switching ringing, efficiency, and ripple, an optimized layout of the TPS565201 is created. This layout can be used for the TPS56x20x series family.
